Description

The main part of this course will provide a basic understanding of the behaviour of fluids on the macro- and micro-scale, where students are able to design pipe and pumping systems for single-phase fluids. There is also an introduction to the SI system of units, dimensional analysis and scale-up.

Basic concepts: fluid mechanics, liquids and gases, stress/force/mass, properties of fluids (viscosity, surface tension).

The SI system for chemical and process engineering and unit conversions.

Dimensional analysis of the variables used in chemical and process engineering systems.

Static systems: pressure, manometry, atmospheric pressure, barometry.

Dynamic systems
• Bernoulli’s equation: applications of Bernoulli to flow measurement, including pitot tube, orifice, venturi, weir and rotameter
• Friction
• Pipe flow: laminar flow, turbulent flow, velocity profiles, pressure losses in pipes and fittings, non-circular ducts, double integrals to determine area

Scale up

Pumping
• Pumps: pump sizing, net positive suction head, complete system design
• Control of flow with valves and variable speed

Pipe networks

Optimal pipe diameter and economic analysis

Buoyancy and drag

Compressible flow

Introduction to Microfluidics

Learning Outcomes

Course Objectives
At the completion of the course students will be able to
1. Convert old units to SI for quantities commonly encountered in chemical engineering.
2. Carry out calculations for fluid mechanics involving static pressure, pipe flow profiles and pressure drop, pumping and other related topics.
3. Understand different types of flow measurement.
4. Work as a team for the creative design of a “water feature” and for lab work and reporting.
5. Write professional reports for an appropriate audience
6. Be proficient at using Excel for fluid mechanics calculations.
7. Have a practical understanding of uncertainties as seen in a laboratory flow system.

Prerequisites

Subject to approval of the Dean of Engineering and Forestry.

Assessment

Assessment Due Date Percentage  Description
Assignments 10% 2 Assignments worth 5% each : Assignment 1 - Unit conversions, viscosity, fluid statics, due Friday March 15th, 5pm Assignment 2 - Pumps, complete systems and compressible flow, due Friday 17th May, 5pm
Final Exam 55%
Laboratories 15% There are two lab components in this course. Attendance to both is compulsory, and each group member must sign the submitted report. 5% Civil Engineering fluids lab (group report) due 1 week after the lab, 5pm 10% Water feature group project broken into milestones: 1% project scoping due Friday May 3rd, 1% Final design due Friday 10th May, 3% WF demonstration Tuesday 28th May, 5% design report due Friday 31st May, 5pm Peer assessment will be used in the water feature project to generate an individual grade for each student.
Test 26 Apr 2018 20% A 90 minute test on content taught in weeks 1-6 will be held on Tuesday 2nd April. You will need a calculator for this test (stickered calculator is not required).


Course Requirements
Both labs must be attended to pass the course. Both lab reports must be handed in and completed to a satisfactory standard to pass the course.  Each student must sign submitted lab reports. Late reports and assignments will be penalised 25% per day after the due date.

Laboratories
Fluid Flow Lab: There will be one afternoon for each student to investigate pumping and flow measurement in the Civil Engineering Fluids Laboratory in the second term.  Students will work as a team.  A group report will be required.

Water Feature: During term 2, students will work in groups of 5 or 6 to design and build a water feature.  In the last week of the semester, each group will demonstrate their water feature.  A group report will be required.

Notes

This is a core chemical engineering course and is a prerequisite of ENCH393.

Additional Course Outline Information

Academic integrity

Course Policies on Collaboration and Cheating
Solving problems in small teams and collaborative learning when working on assignments is encouraged.  However direct copying will result in reduced or zero marks for all students involved.  The assignments are mainly a tool to prepare you for the exams. We advise you to try them individually before collaborating in groups.

General Policies of the Department
Students may obtain the general policies of the University on matters such as special consideration applications, appeal procedures, reconsideration of grades and special provision for students with disabilities from the University Calendar

Assessment and grading system

Assignments (10%)
Two assignments will be given out throughout the semester and will be supported by tutorials.  The assignments are to be handed in to assignment boxes on the 4th floor of the Link building (CAPE academic offices)

5% Assignment 1 – Unit conversions, viscosity, fluid statics, due Friday March 15th, 5pm
5% Assignment 2 – Pumps, complete systems and compressible flow, due Friday 17th May, 5pm        

Laboratories (15%)
There are two lab components in this course.  Attendance to both is compulsory, and each group member must sign the submitted report.

5% Civil engineering fluids lab (group report) due 1 week after the lab, 5pm
10% Water feature group project broken in to milestones: 1% project scoping due Friday May 3rd, 1% Final design due Friday 10th May, 3% WF demonstration Tuesday 28th May, 5% design report due Friday 31st May, 5pm

Peer assessment will be used in water feature project to generate an individual grade for each student.

Test (20%)
A 90 minute test on content taught in weeks 1 – 6 will be held on Tuesday 2nd April.  You will need a calculator for this test (stickered calculator is required).

Final Examination (55%)

All assessment marks might be scaled to ensure that a reasonable range of grades is obtained when the University Grading Scale is applied.  Students should not rely on their raw marks.  A mark of 40% in the exam is required to pass this course.

Late submission of work

Late submissions will lose 25% grade per day overdue.
